Change the DisablePasswordChange registry key to 1 to avoid the Ghost image going out of date in 7 days when the workstation account password changes on the server.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters]
"DisablePasswordChange"=dword:00000001
Note:
this will work only if your network does not try to change this
setting via GPO!! otherwise you'll have to rebuild a new image OR
manually un-join (ie join a workgroup) and rejoin the domain.
